2 Claims.

This invention relates to ventilators and'particularly to means forproviding ventilation for vehicle bodies.

One of the objects of the invention is to provide efficient ventilation,without objectionable drafts, for automobile bodies. Another objectis toprovide simple, inexpensive means for accomplishing the desired result,and avoiding the use of sight-obstructing frames or bars such as are nowrequired in the winged type of ventilation.

My construction has the advantage of being easy to install, simple anddurable, and efiicient for ventilation purposes and protection ofpassengers from rain. The ventilator does not interfere with completeclosing of the window with which it is associated, and it may beinstalled without requiring alteration of any part of the regular windowconstruction excepting part of the frame located inwardly of the windowpane.

In the drawing: 1 Fig. 1 is a side elevation of part of an automobilebody embodying my invention.

Fig. 2 is an enlarged verticalsection taken through one of the frontside windows and frame,

. ,on the line 2-2 of Fig. 1.

' Fig. 3 is an enlarged horizontal section taken on the line 33 of Fig.2.

Fig. 4 is an enlarged vertical section taken on the line 44 of Fig. 2.

In that embodiment of my invention shown in the drawing, the automobileID has a door II and window I2. The window pane 13 of glass is mountedinwardly of the external frame It, in a familiar manner, and is adaptedto be raised and lowered relatively to the frame It. The pane l3 slidesin padded grooves I5 formed in each side of the window between thespaced apart outer frame I l and inner frame l6, and when raised intoits uppermost position, completely closing the window opening l2, thepane I3 fits into the horizontal groove I! formed between the uppercross piece !8 of the outer frame [4 and the upper cross piece IQ of theinner frame Hi. The sill of the outer frame is indicated at M and of theinner frame at 16'.

The upper cross piece IQ of the inner frame I6 is grooved as indicatedat 20, and the upper portions of the side members of the frame l6 aresimilarly grooved as indicated at 2! to receive a short depending paneor shield 22 preferably made of non-shatterable glass. The grooves 20and 2| are padded as are the grooves I5 and IT. The upper and side edgesof the shield 22 fit in the grooves 20 and 2|, and the lower edge of theshield, at each end, rests on a shoulder 23 at the lower end of eachside groove 2|.

The shield 23 is preferably three to three and one-halfinches in itsvertical dimension, extends across the window opening, and is locatedabout one-half to three-quarters inch inwardly of the pane l3 andparallel therewith.

To install my ventilator in a standard motor car having a slidablewindow pane, it is necessary only to groove the upper portions of theside members of the inner frame I6 and the cross piece I 9 of said frameI6, and to remove one of the side members. The shield may then beslipped into the groove 2i of the unremoved side member, to rest on theshoulder 23, and into the horizontal groove 20. When thus positioned theremoved side member of the frame IGmay be replaced with its shoulder 23also supporting the shield, and it is then secured to the car body inthe usual manner.

When the window pane I3 is lowered to a point above the lower edge ofthe shield 22, air currents will strike the shield 22 and passdownwardly and rearwardly into the car, the passage of air into themoving car, through the space between the pane l3 and shield 22 beingconfined to that part of the space located opposite the rearward half ofthe shield. This is due to the fact that, as the car moves forwardly, anarea of negative pressure is produced rearwardly of the front sideframes I l, adjacent the forward portion of the window pane l3, whichdraws the stale air out through the forward portion of the passagewaybetween pane l3 and shield 22. Thus the car is eificiently ventilated,without undue draft and without obstruction of view.

The shield may be easily removed or replaced, and the installationrequires no operating handles or brackets such as are used in the wingedtype ventilators.

Changes may be made in details of construction without departing fromthe scope of my invention and I do not intend to be limited to the exactform shown and described, except as set forth in the appended claims.

I claim:-

1. In a vehicle, ventilating means comprising a window, inner and outerframes, a window pane movable between the framesin a vertical plane forclosing the window, the inner frame having a groove in its upper crosspiece and in the upper portions of its two side members, and a shieldlocated in said grooves in said inner frame members, and depending fromthe cross piece slightper portions of its two side members, a shoulder15'' inwardly of the window pane. at the lower end. of each of said lastmentioned 2. In avehicle', ventilating means comprising grooves, and ashield located in said grooves in a window, inner and outer frames, aWindow pane said inner frame members, and depending from 5 movablebetween the frames in a vertical plane the cross piece slightly inwardlyof the window for closing theflwindow, the inner frame having pane andresting at each end on saidshoulders.

a groove in its upper' cross piece and in the up- DAVID WILSON.
